Cyclohexane

C₆H₁₂

IUPAC: Cyclohexane

CAS: 110-82-7

Overview

Cyclohexane is a cyclic saturated hydrocarbon that adopts a chair conformation to minimize ring strain. It is produced primarily by hydrogenation of benzene and is an important intermediate in nylon production (via cyclohexanone and adipic acid).
